单词	stereospecific
释义	stereospecific /ˌstɛrɪəʊspɪˈsɪfɪk / /ˌstɪərɪəʊspɪˈsɪfɪk/ adjective Chemistry Another term for stereoselective.Enzymes have been widely praised for their specificity and efficiency in stereospecific catalysis.... Third, the reactions are ordinarily very stereospecific. This observation seems inconsistent with the hypothesis that myosin heads bind to actin in a stereospecific conformation in low ionic strength relaxing conditions. Derivatives stereospecifically adverb ... The result is that the hydration of fumarate proceeds stereospecifically with the production of L-malate. Acid-catalyzed hydrolysis of the C - 6 methyl enol ether affords codeinone, which may be stereospecifically reduced with sodium borohydride to codeine. Nevertheless, the data presented here are consistent with the idea that during isometric contraction a large fraction of cross-bridges is stereospecifically attached to actin in a nonrigor-like conformation. stereospecificity /ˌstɛrɪəʊspɛsɪˈfɪsɪti/ /ˌstɪərɪəʊspɛsɪˈfɪsɪti/ noun ... For the first time, we observe that the acyl binding site of cholesterol esterase shows stereospecificity for diastereomeric inhibitors. While this lack of stereospecificity does not establish that the oxidation is artefactual (the chiral centre is five bonds away from the aldehyde group) it was, nevertheless, cause for disquiet. However, further experimental verification of label stereospecificity will be provided by bifunctional spin probes whose orientation and mobility are restricted by two attachment sites.
